07 rubi is way more capable off road
more comfortable on more road
al around it is better except for the hummer look, but that can be fixed with a few mods like lift, tube fenders etc.
if i had the money to choose wich one i wanted id get the 07 rubi in a flash, now if your comparing the 05 unlimited to the 07 unlimited (not rubi) then i would go with the 05
